Assign Task to Sales Reps who does not own the contact

We are exploring a potential way we can assign a task to a Solution Rep based on the solution that the contact might be interested.  We have 4 different solution reps assigned to  each account.

I understand that out of the box, we can only assign tasks to Contact Owner or we need to explicitly assign to a specific SFDC user. However looking at the assignment from the Marketo side (See Below), there might be a potential way we can do this., if we can get the  “Owner Person ID”.

This ID is different than the SFDC ID and I am not sure if Marketo has the capability to see this ID.
