Yes!
You can apply different levels of carried interest to your investors in the same SPV.
In order to do so, you can:
Go to your deal's page
Click on the commitment tab
Select the commitment that you would like to edit
Click on "Carried interest", and enter the new value you'd like to apply
You can only edit commitments after your investor has committed, which means that you can only edit a commitment that is "Pending approval" or "Approved commitment".
You cannot modify the future carried interest of a user still in the "Requested Access" or "Awaiting answers" buckets.
