Option to make Weeping Vines-like plants in the "Plants" mod element.

I have recently been trying to add a plant that acts like the Weeping Vines block added in the 1.16 Nether Update. (Ex. have it only placeable on the bottom of blocks, grow infinitely, change from a small state to large state depending on how many blocks are attached, basically work like the "growable plant" but upside down.) As far as I can tell, this is extremely hard, if not impossible, with MCreator's current features.

What could really be useful is a fourth type of plant that mimics the physics of the Weeping Vines.
