This has been requested before, but it is not as easy as it sounds.
Subversion does not support multiple merge ranges in that way, so TSVN
would have to perform a merge for each revision range you specify. If
one of those merges results in a conflict, the only thing it can do is
stop with only some of the merges completed. And as SVN doesn't have
merge tracking, it's up to you then to sort out the conflict and
remember which of the revisions you still need to merge.

I suppose TSVN could grow a dialog which lists the revision ranges and
ticks them off as each merge is completed, allowing you to sort out any
conflicts as you go. But that sounds like a lot of work to me, and it
probably sounds like a *huge* amount to Stefan ;-)
