show <name> tags from a gpx with several <trk>

[kosi2711]

Hello everybody!
I create a large GPX file with scripts from the individual GPX
files of my hiking guides. This file contains all tracks:

... <wpt lat ...> <name>Kors_81_PagliaOrba(2525m)(Top,schwarz,8h30m).gpx</name> <desc>Kors_81_PagliaOrba(2525m)(Top,schwarz,8h30m).gpx</desc> <extensions> <show_arrows>true</show_arrows> <osmand:color>#FF000000</osmand:color> <osmand:icon>special_trekking</osmand:icon> <osmand:background>square</osmand:background> </extensions> </wpt> ... <wpt lat ...> ... ... <trk> <name>Kors_81_PagliaOrba(2525m)(Top,schwarz,8h30m).gpx</name> <desc>Kors_81_PagliaOrba(2525m)(Top,schwarz,8h30m).gpx</desc> <extensions> <show_arrows>true</show_arrows> <osmand:color>#59000000</osmand:color> </extensions> <trkseg> <trkpt lat...</trkpt> <trkpt lat...</trkpt> ... </trkseg> </trk> <trk> ... </trk> ... ...

This has been working fine for years, see the attached Osmand
screenshot:

But there is one thing that annoys me:

„zz-z31-Rother-Korsika-2“ is the name of the GPX file. This
is a useless information – it would be perfect, if, when
tapping on the route (and not only when tapping on the icon)
the tag „Kors_81_PagliaOrba(2525m)
(Top,schwarz,8h30m).gpx“ would be shown (Apps/Programs like
Gpxsee or Gpxviewer do so). Is this possible?

Maybe someone can help me? Thank you and greets!
