I would like to connect Dynamics Sales with Brevo and have installed the Premium Connector. The normal matching of data fields of the same data type already works well.

But now I have the challenge that some data fields within Dynamics are custom data fields that were created as drop-downs.
In the Brevo table, however, it is a text field.

I did some research in Zapier this morning but didn't really find the right solution, for example how to convert the data into the correct formats during an update of a data record.

Example update process would be 

I change a lead in Dynamics - Zapier trigger "Update" reacts correctly.
While the data is now to be updated in the Brevo list, a drop-down field (for example Salutation) in Dynamics (example Mister = 1; Mrs=2; Divers=3) must receive the entry of a text field in the Brevo field Salutation (i.e. Mister or Mrs or divers) in an intermediate step.

I don't know exactly how this conversion works.

Can anyone here give me a hint. That would be great
