Batch processing of imported files to select e.g. the category, difficulty

[update-freak]

Hi developer

it would be good to have batch processing of imported files to select e.g. the category, difficulty is possible.
For example when I add 200 GPX files it would be good to define rules, e.g.

with name "Rundtour" -> category: biking
with name "Rundweg" -> category: hiking

or high difference up > 1000m and high difference down > 1000m => difficulty hard

or distance > 50km and category biking => difficulty hard
or distance > 20km and category hiking => difficulty hard

or put all tracks to public
