No, but there's one important thing to remember.
For songs registered with PRO accounts, digital distributors (e.g. CdBaby, TuneCore, etc.) hold 50% of the publishing rights and songs are registered with the specified collecting society.
Therefore, in the registration phase of your song in Soundreef, you can assign yourself and your co-songwriters up to 50% of the shares you're entitled to and you have to mention the distributor as the rights-holder for the publishing rights.
