We have a situation where there are 3 developers working on 3 feature branches. All three developers contributed to a single CSS utility file. Now we are in a situation where the features are incomplete but we need to sync just this utility file across all 3 branches because none of the features can be completed with out the merged file.
What should have happened is that the utility file should have been completed on its own feature branch then merged back in, and they the 3 branches would branch from that point in time but that didnt happen unfortunately.
Is there a way to sync a single file across branches?
