placeit | Get closest to the right answer – in meters

I have created a big macro in MS Word VBA that loops through many tables and inline shapes and with the help of copy-paste rearranges them after some manipulation. The problem arises when more than 50-60 tables and shapes, the macro takes 60 seconds to finish and i get random crashes (about 10-20% of the time) that i suspect come from clipboard overload issues and too much use of "Select". It was suggested to me to just use collections to store the shapes and tables (which worked) and improve the code, that i am currently trying to do, but i cant find the method or way to make the collection items appear in Word.

I am asking for something like collect(1).Show, which would work at the current selected paragraph or at least a collect(1).PlaceIt(there) method that i can input the coordinates of paragraphs i want the Shape or Table to appear in.
