BounceBlocks auto trigger option

**Is your feature request related to a problem? Please describe.**

Just to this when players walk into bounce blocks (automated) like slime block that is used as "jump pad" on spawn, then they have to jump on it, so they don't even know it's bounce block.

**Describe the solution you'd like**

Would be nice if you add way to set auto trigger option to whole section of bounce blocks and ALSO to exact blocks in auto blocks, so slime_block: "1,1,0, trigger" or something like this.
**Describe alternatives you've considered**

New mechanism called jump pads?
