ButtonSelect options update at runtime

I am using a dhtmlxRibbon in which i have added a buttonSelect.
At runtime i need to update the options listed in that buttonSelect.
Is this possible without recreating the ribbon ?
I am searching for something like the functionality in dhtmlXCombo based on addOption and removeOption.

Unfortunately such feature is not supported in dhtmlxRibbon

Thank you for the answer.

I managed to solve this by setting the inner menu for the buttonSelect to null.
At some point during the page loading the menu gets updated with the new options.
I write this just in case somebody hits the same issue.

Have a good day !
