How to adjust indent increments?

[organizing 2]

When I select a few lines of text, and then select to Increase Indent or Decrease Indent, the selected text will move in-or-out by a certain amount.
How can I increase or decrease the amount that selected text is moved in-or-out?

Thanks,
Doug

Hi. It's possible to use the indent toggle repeatedly to 'tab' out to a deeper level,  but it's not currently possible to select how far one click on the icon will take you.
