Best shot and the quick one would be to test by append table to LQUA, where you will maintain
field MAKTX (40 chars) and fill it up occasionally from MAKT table (background job).
For the test you can update it by SE16N => &sap_edit to shorten the process.
Then see if you will get an option in LT10 to import the field in the list.
If not then you might need to do additional coding to make it work, but it will be
risky because if some new updates overwrite standard SAP code in LT10 you'll lose
your functionality and have to redo it again.
It might work without additional coding if SAP coded to include all the fields from LQUA
to be possible to put them in the list view in LT10.
There could be a few more approaches but this is is the fastest and easiest and the one I'd
take first, and if it doesn't work maybe try finding a user exit for this but I doubt there is one.
Regards.
