I like the system of multiple gmail labels but am concerned about space used. I think that TB stores a separate copy of the whole email in every folder corresponding to a gmail label [including a copy in the "allmail" folder along with a separate copy in the each of the other folders].

Can I arrange to store a single copy of the email in TB,[perhaps in the allmail folder] with a shortcut type pointer from the individual folders to that single copy.[i.e for every email with one gmail label [eg personal] there are already 2 copies in TB, one in the allmail folder and a second in the "personal" folder
