Narrative:

We had to de-ice due to some residual ice on winglets; leading edge of the wings; leading edge of the tail and horizontal stabilizers. Proceeded as per SOP with de-ice procedure and appropriate checklists. During taxi to the runway I requested a runway performance change checklist; since the assigned runway was different from the one discussed in the briefing; and the first officer reading through the checklist positioned flaps on 2 as per takeoff performances. We realized that was not standard procedure for the post de-ice taxi to set the flaps which shall be positioned at the right configuration during the 'before takeoff checklist'. I requested a before takeoff checklist immediately with no other issue.the checklist dedicated to the de-ice procedure requires the crew to verify flaps settings against the takeoff performance data and verify the actual position during the 'runway performance change checklist' when the flaps are supposed to be up.the very confusing de-ice/anti-ice checklist could have posed a serious safety issue; affecting the anti-ice fluid; in case of actual freezing precipitation or prolonged taxi on contaminated surfaces. Revise and update the appropriate checklist which is very confusing
