Hey Carsten,
It’s not only a good idea - it’s actually something that’s in the works right now.
The logic we followed in the current iteration is that one where a ‘MQL’ indicates that the lead has been qualified, to such an extent that it can sync over to Dynamics - and it no longer needs to be qualified in Dynamics, hence, it can directly become a contact.
We definitely acknowledge this doesn’t cover all the nuances. While it helped most implementations, it doesn’t cover all of them. Future: Making it possible for you in the sync setup to classify which leads make it over is going to give you that flexibility. We expect to release that this year still.
