[TYPO3-templavoila] FCE specific RTE config

[Chris]

Hello,

I first asked this question on the RTE list, maybe it belongs here ?

I have a FCE in which I want to display just a few RTE buttons, so I put 
this in the Data Structure :
<defaultExtras>richtext[strong|emphasis|textcolor]:rte_transform[flag=rte_enabled|mode=ts_css]</defaultExtras>

but when editing I have all the buttons as set in my Page TS Config

Is there any other way to show only my three buttons ?

regards,

Chris
