How about adding a link date tag while ignoring the other possible tags.
eg:
existing files
myfile[tag1 tag3].md
myfile[tag1 tag2].md -> this to link
on link creation
myfile[tag1 tag2 linked20150101].md
identification using name, link tag and extension
myfilename + linked20150101 + md
1. this can be used even if files have the same name
2. and tags still can be added
3. it is the users responsibility to not delete the linked tag
