While using 2 goal plans, the weightage is getting added equally for both the goal plans

In the Performance Templates section of the performance goals, we have allocated a weight of 50%. However, since there are two goal plans, each plan is assigned an equal weight. For example, if the total weight for performance goals is 50%, both Goal 1 and Goal 2 each receive a weight of 50%. Here, we are facing the issue as we don't want each goal plan to be weight 50%, the total performance goal should weight 50% .
Can we adjust the weightage for each goal plans?
