What can be done for stubborn tooth after Invisalign? (photo)

i am done w all trays finally except 1 tooth needs to drop down a tad more. we've come to point where metal bracket put on w use of rubber bands to pull it down .. it's been almost 2 weeks & I don't see improvement. I'm frustrated & disappointed w this . everything went well entire time now this. can a wire be put on to pull it down vs rubber bands ? I'd rather be aggressive at this point . dr & invisalign felt this was best route vs taking more impressions which were already done mid course .
