ofxControlPanel - addMultiToggle - how to set value

First of all, thanks Theo for this great addon.

vector<string> paleta;  
for (int a=0; a<6; a++)  
gui.addMultiToggle("paleta", "paleta", 0, paleta);	  
gui.setValueI("paleta", 2);  

I wanted to know how to set a determined value in addMultiToggle, in this particular case I want to be able to change selected options pressing (1-5) keys

Thank you!
