Want to use specific pages on multiple index pages

Site URL: https://simplyrepair.uk

Hi there! For the sake of simplicity and easy updatability in the future, is there a way I can link multiple sub pages from an index page into another index page?

I'm basically looking to combine only two pages that we use on our homepage (index page) which would be /repair-services and /contact onto a new index page. Is that possible somehow?

I was thinking about using linked pages, but that option doesn't exist for index pages

thank you!
