I think this should work
Go to "Part List"
Set the "!LDRAW_ORG Type" to "Subpart"
Add a Filter "Author" select yourself "WUIt"
Add another Filter "Body" set opertator to "Contains" Text "rect"
That gives around 40 parts
But honestly if a rect has only integers or 2 decimals I would not bother changing it.
THe other reasonstated that edge lines might be doubled, can be found, same argement then also for the boxes...
