Worflow order of a sync project


We have an issue with the workflow order of a connector made with Starling.

We have 2 workflows in this order: the first one for inserting identities and a second one for updating a boolean custom field.

The problem is that during the first sync, it inserts all the identities without then performing the update of this custom field.

And if I do the second sync, the update of the custom field starts for the identities.

 I would like the update to start immediately after the insert, as specified in the workflow order.

Any suggestion?

Thank you,
