I know, you are again picking raisins from the cake. It is self understood that a 90-days report can be made on any Immigration anywhere in Thailand where you are actually residing at a given point. It is not connected to the stay permit or the visa. Somebody who travels through Thailand and lives in hotels or guesthouses will have to talk to the managers in order to take at least a screenshot of their TM30, before doing the report.
