Merging Nets on inserted Design Blocks

Attached, please find a PDF of our issue.
We have an RGB Smart LED Controler (LPD8806) and 2 RGB LEDs in a Design Block. We re-use the design block in daisy-chain connectivity style to build out a 500mm strip of 13 DBs. The Data In and Clock In signals feed the IC, and it outputs to the next Design Block via Data Out and Clock Out.
We number the nets with a 2-digit suffix and the Design Block has -00. Once subsequent blocks are inserted, we spin the numbers on the output side. Our problem is that we need the subsequent block's input to take the net names from the outputs of the previous block. The other direction of net name precedence does not work.
Is there a way to pre-set the precedence in net name survival on a merge?
