Log4OM

I'm guessing this is not possible at the moment (love to be corrected!) but my OCD would like to see all 6 figure locators all upper case. When I import my contest QSOs and upload them, always upper case.
I note live QSO upload sents my locator with last two letters lower case. When I enter my details Log4OM forces those lower case regardless of what I type.
Be good to be able to choose preference.

The correct Gridsuare uses lowercase letters after the numbers.
ADIF 3 standard is linking to this wikipedia if you hit Gridsquare at the ADIF site:

This is the "standard" format for gridsquare locator. What is the application that doesn't accept the lowercase?
