When creating a formula you're given the option to "Reference Another Sheet".
I love this feature but it needs improvement because it ONLY gives you the option to create a new reference.
Yes, you can click the same range as an existing range and it will auto-populate with the correct range number, but that's only if you remember the exact range.
What if you changed the options?
Instead of "Reference Another Sheet" give two options:
Example if "Create a Reference to Another Sheet"
Eample if "Select an existing sheet Reference" is selected:
Alternatively, you could keep the same "Reference Another Sheet" option but display the existing sheet references immediately, but also allow the user to browse to the sheet/range they wish to create a new reference from.
PS. The browse window for creating a new sheet reference should always default to the current workspace!
