Populate List collector into a related list.

Hello SNC, 

 I have created a catalog form and it has a list collector variable which is refering to task table and my reference qualifier will filter the items, Everything is fine untill this point.

Now in the RITM created, I want all the selected items from the list collector(which are shown in the variables section) should be populated as individual items in the related list.

Please let me know how this can be achieved.

TIA
