Is possible to split and remove audio track when no video?

Usually I external record audio signal without cuts (all sesion as one only audio track clip)
At the same time, I get several clips in camera (video+audio reference)
Place all the clips in a timeline positioning every clip in their Timecode so I get 2 tracks:
First track have the camera clips: clip, gap, clip, gap, clip, gap. etc.
Second track is on clip only with audio only timecode synced.
How can get de second track to be splited and removed (gap space) when there are not camera clips in first track?

(I know I can get synced an embedded audio from second track to add a embedded track in the cllips in the first track but in this case I don't want that)

Manually move to the gaps and cut out those sections from the long audio clip.
