Timeline Start later 2

I refer to the following thread, but unfortunately it is closed, so I can’t write anything more in it.

Timeline Start later

I’ve gotten into the habit of not having the songs in Ardor start at the beginning of the timeline, but at approx. of a minute. How can I tell Ardor that he’s putting the first bar of the ruler on my song starter?

I have the following problem: I started a song. There are many time changes in the song (I constantly change between 3/4 and 3/4, in between there are also 5/4 bars and 2/4 bars - so quite complicated).

Now I noticed that I forgot to insert a BBT marker at the start of the song, as described in the other thread, so that my song start is at bar 32. If I want to add a BBT marker later, it moves the other markers with the tempo and beat changes. Is there any trick on how I can set the song start to bar 1 afterwards without having to adjust all subsequent tempo and beat changes individually by hand.
