How do clients book multiple but different treatments in the same appointment?

Hi, we are a body sugaring studio offering many services on our scheduling page.

i.e. If a customer wants to book an upper lip (treatment #1) with a brazilian (treatment #2) how do they do this in acuity scheduling?

...the "add a time" pop-up only let's you book the same treatment twice, not a different one.

Thank you.

I'm very curious about this too! I haven't found a way.

I have a similar question but it differs from yours a bit - not sure if I should choose ACUITY Scheduling or Squarespace Scheduling for my design?   I need the following scheduling function;

Client books an appointment (Category), which require he/she selects 3 different days/time in total - when client has selected available dates, he/she pays a total set amount ($) and go to checkout. After checkout is complete, the client should also be able to cancel/change all three appointments based upon availability. 

Can this be done out of the box? I did consider setting up a package solution, but Squarespace doesn't allow one to test this feature... so not sure if it is worth upgrading to a premium service that might not be able to do the work anyway... Suggestions appreciated :-)

Did anyone ever find a solution to this?

Is there a solution to this, same problem here

has anyone found a solution to this problem?

Has this ever been answered? Finding Acuity very frustrating to setup. 

Is it possible to for user or client book multiple treatments per booking??

Eg Lip Wax and Brow Shape?

We use add ons to achieve this. Basically if it's a service that they can add when getting another service, we add the $$ and duration and select which services they can add it to. This ensures they only get one confirmation email and one text reminder etc. We also have them as a stand alone appointment so they can book just the add on item as well. 

It suggests to do as add on’s but I tried it and it would be  another long list to make.
