Description column, selecting what is calculated

Are we able to chose what the description column calculates? I usually like the column and have it on by default. However when I open a large folder of text files it will go through and check the file type for each one. I don't find the output useful but I don't want to turn off the column.
So I find I have to remove the column and re-load the lister.

I would love a page in the option to pick what calculations it runs, so i can turn off the expensive ones i don't need.

There's a little control over the types of information shown, via Preferences / Miscellaneous / Advanced [Information Display]: desc_show_info:

That would always include the "UTF-16" type descriptions for text files though, so it's probably no help here.


Thanks leo
