Insert Quantized Markers on the fly...

How about having the marker insert button being able to ‘snap to grid’.
When starting a new song with a client songwriter, usually we first record the song to a click track as he plays piano. As he sings the song, I hit the ‘insert’ button at the start of a verse, chorus or bridge. He finishes the song and then I have to go through the complete song, naming the markers and then aligning them to the grid.
You have an ‘auto-quantize’ feature when recording midi…why not the same for markers.
