Can modifications be made to the Periodicity Toolbar so that it can be customized to have any time frame the user chooses? If the software developers are not doing this, then how can I have access to the part of the code that controls this so that I can make modifications my self?

I would like to change the time frames on the fly and have 1M 2M 3M 4M 7M 16M etc if I wanted.

Thank you
