Yes, signed quite a few after completing LSTs on pilots destined for a U.K. airline - some going for ZFT and some requiring base training afterwards. The SRG 1100 enables them to carry on down whichever route they need to follow.
sure, the other SRG forms you mention are required and I believe that when all are complete, the ‘candidate’ uploads all of them to the CAA for issue of the appropriate rating.
