Select the same region in another sequence in an alignment

Scenario:

1. Open an alignment in the UGENE Alignment Editor.
2. Select a region in some sequence(s) (e.g. columns 10..200).
3. Hold Ctrl key (or Cmd on macOS) and click on a sequence name.
   Current result: the whole sequence is selected.
   Required modification: the region (e.g. 100..200) in the clicked sequence is selected. There is no more selection in the previously selected sequence.

Consider similar scenarios when:

• several sequences are selected at once using:
  • mouse
  • Shift hotkey is used
• the clicked sequence(s) is within/intersect the sequence(s) that were selected initially.
