Auto selection of some values of Checkbox group in Lotus Xpages

I am using a checkbox group whose values are populated from the back end configuration . The checkbox group is for selection of Lab parameters . In the configuration , I kept status of some parameter's as disabled and some parameters are enabled (with the usage of status field ). checkbox group brings all the disabled and enabled lab parameters . By default , I want the auto selection of those Lab parameters that are set as enabled i.e enabled parameters are auto selected in checkbox group. Is there any way to have some checked ( auto selected) values in the checkbox group .
