While implementing the new Move Dialog UX, I got an interesting clarifying question from my Coding Agent:

For Move, if the user has multiple accounts/capabilities, should the workflow require one currently selected signing account to have write permission on both the source document and target parent, or can the app combine permissions from different accounts?

The Context is the next:

the desktop app can hold multiple accounts
"Account A" have writing capabilities in "Site A"
"Account B" have writing capabilities in "Site B"
I want to move "Doc A" from "Site A" to "Site B"

Because the system knows the current user have Write access to Both Sites but with different accounts, should we let the user do this? or should we Limit moves to Accounts that have Writing capabilities to both the source and the target paths?
