Option to select Co-signer seed on the app.

Hello.
I have this issue about using seed created in Gordian seed tool to sign a multi-sig transaction. I have 2 seeds created in the app, and using those seeds with another seed on sparrow-wallet to created a multi-sig wallet. When I try to do a test to send a transaction and co-signing with seed on Gordian app, it is signing the transaction with both seeds at the same time instead of letting me select which seed I want to use to sign the transaction. My question is, is there a way to select a particular seed to co-sign a multi-sig transaction on Gordian seed tool app? sorry I hope this make sense English is not my first language.
