How can I clear OFS_Trend assumption values in data forms

Summary:

OFS_Trends are used in our planning forms and values selected in all our forms are for UAT purposes. Now we would like to clear all data values as well as Trend assumptions in preparation for move to prod, but the data clear rule clears only data values under OFS_Total Plan member. It does not clear the trend values that have been selected.

Is the only way to clear them is to select 'clear trend' manually against each combination? or is there a better way?
