Geometry Parameter - Set Multiple Objects

Hi there,

I have been wondering for a while, after we have set multiple geometries for a parameter, can we keep on adding multiple geometries? Say if we have set 100 points to the point parameter, can we go to the 'Manage Point collection' to add another 50 points? Seems the 'Add Item' and the 'Add Path' can only add one point in one go...

I know that you can always use a 'Merge' component to add multiple point sets together.

But once upon a time my Grasshopper goes haywire and I can keep adding multiple geometries whenever I want, I found that it is quite handy and it can keep your canvas clean and tidy.

It there a specific way to make it 'go haywire' again? 

Thanks for any suggestion
