Row selection on Spreadsheet widget

Hello,
We have noticed that there is no mouse drag for row selection on spreadsheet widget. Is this something that will be patched on future spreadsheet versions?
Or can you guide us about how to make adjustment to the spreadsheet library so it can have this ability. basically we want :

1- To click and drag mouse on far left of spreadsheet and be able to select multiple rows. currently when we click, we can select one row and we can’t drag to select multiple row.

2- Ability to select multiple separated row [on Mac by pressing command and clicking on multiple row], we can do this on google sheet but not here.

Best regards.
