Hi Jose.
This is not possible in standard though you can try some enhancement.
As per standard, you always want to review the block before really deciding whether to proceed with the transaction or not. License block is a kind of soft block where you can always proceed with the transaction by assigning a valid license whereas SPL block is a kind of hard block but still you always want compliance team to review the block to see if it is not a false block.
Setting up system such that it doesn't create a document if compliance block is encountered doesn't make sense to me.
it would be good if you can provide the business scenario or justification for such requirement.
thanks,
