Source of TAB

Having problems and the Oh Sheet error came up I decided to split my application into two parts.
My app is for Golf Clubs, having the important parts for the volume of information, the sheet that manages the reservation of schedules and the sheet where the user loads the shots. Both sheets between Glide and GSheet columns exceed 1000 columns. The query and request for a new feature, because from what I saw it cannot be done, is that the source of a tab is another Glide application or a URL, what I want to do are two applications and that the end user practically does not realize it’s another app.

Can you think of another option?

Thank you
