Certainly a system with over 50 labels can stand 2 more. But I'm not sure it would be helpful. The point of labelling (at least, when it comes to all those conversions) is to flag what kind of expertise is needed to address the issue. So Councilor A can look at the high-priority open ticket list and quickly see that ticket “output is invalid” is about DOCX, and think “I know absolutely nothing about DOCX” to himself and skip it; whereas Councilor B can look at the same ticket and think to herself “I’m trying to learn the XML format underlying DOCX, maybe I’ll give this one a try”. Doesn’t strike us as particularly useful to separate out whether conversion is to or from DOCX, it is the required expertise in DOCX that we were thinking should be flagged.
Typing on my phone, I see it converted my directional “from TEI” suggestion into quote marks. I meant two right angle brackets for that.
I suppose we could just have, with any conversion, another bank of labels (just two): from TEI to TEI
