Multiple planters, but only one FoliageInstance? How to do multiple and keep them movable?

Note: I’m a complete beginner at this only been experimenting with Unreal for about a month.

It might be easier to show what I’m trying to achieve:
(Warning: Australian Language In Video)

So, I’ve made many planters, and I wish to place plants in them. - I then want the ability to copy/paste and move each planter around, with its individual plants.

The problems I am running into:
Every plant seems to go into the same instance, and are not separate per group.
Cannot move the plants with the planter as a group.

Is there an easy way to do this, or am I just going to have to drag every static mesh of these plants into the planters one at a time, and not use the Foliage tool at all?

It’s been a week, are there any solutions to this?
