Filter all tracks in different folders by ascending elevation

In locus map 3 pro, I find that the filter lacks options.

I have many routes organized in folders, which are themselves located in different groups.

For example, I'd like to filter out routes with more than 1000 m vertical drop :

- within a folder (today, only advanced sorting can classify routes according to this criterion)

- Even better: for all folders in a group or several groups, in a single operation without going into each sub-folder.

Another possibility would be to create a kind of bookmark that saves the sorting and display performed on the folders, as some mapping software (qgis) does.

Thanks
