Select multiple goals and life areas

Often times certain Goals and Subgoals overlap. In my case for example my personal learning goals in a subject overlap with my Sub-Goal of succesfully completing a module at uni. There are countless other cases where such overlaps occur. Thats why the ability for a multiselection of goals (for mutliple life areas) and of sub-goals (for mutliple goals) etc. would be great. This way you can really see how some goals / subgoals help you get ahead in multiple areas at once.
