Allowing Signer to Choose TSP Provider for Qualified Signature

Hello,

I would like to know if there is a way to allow the signer to choose the TSP (Trust Service Provider) when signing with a qualified electronic signature. Currently, the sender must select a specific provider in advance.

Our scenario involves adding recipients from different countries, and in many cases, we do not know the exact TSP provider they have. Is it possible to allow the sender to specify only the type of signature (e.g., qualified or simple electronic) and let the signer select the exact provider during signing?

Any guidance or best practices would be greatly appreciated.

Thank you in advance!
