It would be great if there could be a separate page where any money that has been requested is stored until it is paid.
My brothers always take several months to pay me back for things, so it would be really good if there was a central place these would stay, and somewhere that I would have records of it too.
There is. It’s called shared tabs 
Would the spending need to be done on a shared tab? Maybe I need to look into these a bit more
Go to the Payments area in the app, and click ‘Share’ there are explanations there.
Thank you both! I had a different impression of the shared tabs! Had a good look and it’s perfect! Thank you
