Much-needed missing functionality from Squarespace

We've been up and running with Squarespace for about six months now. We're a pet retailer with three physical shops in the UK and now an online shop. Overall, Squarespace has been a top class experience, however we've noticed a few missing functions we really need:

1 - The ability to select a Fulfilment Profile when creating a product on the mobile app

Our staff post products using the mobile app because they can take photos on their phones of the animals in-store and do it there and then. They don't have access to a laptop and the desktop version. Annoyingly, the mobile app doesn't currently let them choose a Fulfilment Profile, which means I or someone else has to separately set the Fulfilment Profile for each product/animal afterwards on a laptop. Which makes a one-person task a two-person task for each animal posted.

2 - The ability to select store categories when creating a product on the mobile app for Android

Our staff with Android phones can't set store categories when they publish products. It only appears to be available on the iOS app. Which again means I or someone else on a laptop or with iOS has to set the categories for each product after a staff member has published it.

3 - The ability to set a separate SEO page title for store category pages

Our animal category pages are named for visitors when they're on the site and browsing e.g. Geckos, Leopard Geckos, Crested Geckos. However, we know that we could appear in better positions on search engines and attract more valuable clickthroughs if we had separate SEO titles like Geckos For Sale, Leopard Geckos For Sale. But currently we can only set one category name for both.

4 - The ability to use Clearpay with local pickup orders

My guess is Clearpay needs a customer address in order to accept an application, so for local pickup orders the customer doesn't provide an address therefore Clearpay isn't available to them. Our products are live animals, so many customers will pick up in store. However, many of our customers want to use Clearpay.

Couldn't Squarespace or Clearpay ask for an address for local pickup orders if the customer chooses Clearpay at checkout, explaining that it's necessary for the Clearpay application? That way, anyone who doesn't choose Clearpay doesn't enter an address, while anyone who chooses it does - having seen a notice explaining why it's now required.

We've contacted Squarespace multiple times and requested these fundamental features, but when or whether they get implemented, who knows!

Just wondering if anyone else needs these functions as much as we do? Or if anyone's found workarounds? Cheers!
