[Plugin: Ultimate TinyMCE] Button for adding custom fields?

Could you be a little more specific for me? How exactly would you like it to function?

just like there is button for hyperlink or add image …

when pressed to get the popup with options
field name:
value:

reason is that I cannot reach custom fields any other way then thru text editor buttons … if possible…
