The only way to do what you’re asking is to create a custom form. Form screens in Glide are a one-time use sort of thing and don’t have a “Save Draft” ability.
I’m just dropping this here so I have something to refer people to when they ask.
This is a simple concept app (copyable), that demonstrates the following techniques:
Building custom forms for adding and editing list items (as an alternative to the native forms provided by Glide)
Preventing duplicate new entries using User Specific Columns and Relations
Enforcing mandatory input items
The use of visibility conditions and user specific booleans to control user flow
There is nothing particular…
