Bad time signature import

I tried to import on LMMS (the latest stable release) the MIDI file of a song that i exported from a score editor (Musescore, guitar pro, etc.). The song blends measures in both 4/4 and 1/4. After importing it on LMMS i realised the time signature changes weren't imported which messed up the whole song. Everything is off-grid.

I think it would be great if the time signatures were correctly imported considering it s one of the chore basis of all written music.

EDIT : i rephrase : it would be great if we could use more than one time signature per song.

Reproduce the issue in LMMS by importing a MIDI file exported from MuseScore or Guitar Pro that changes between 4/4 and 1/4. Trace how the imported song represents time signatures and verify whether the grid follows each change. Done means songs with multiple time signatures retain those changes after import and remain correctly aligned to the grid.
