and you are trying to align the pdn vertical strips ?

I think rather than going in this direction you can do the following:
1. Harden your design/macro without using metal5
2. And use vertical straps of metal4 in your macro for power, dont use horizontal straps
3. When inserting the macro in userwrapper, block met1/2/3/4 for macro in pdn.tcl
4. Horizontal straps of user wrapper would then overlap the macro placing vias for power connection.

@User how do I block the metal layers ?

seems that worked just limiting the number of layers to 4 (in fact the default value is 5 for the user project example)
however <I still got LVS error
LVS tells me that on the layout i have my vccd1 connected to vssd2
