question about stage builder.

[Avion-Finch]

There are two stages I was wanting to make, and I want to know if theres any stage pieces that
1. work as portals(like warp pipes in the old SMB stage)
2. barriers that appear and dissapear, (mostly vertical)
I was thinking of making two certian wii game based stages :)

I don't think so.

I don't even know if you can choose your spawn point.

I didn't saw those, sorry.

aw, I guess Im gonna have to make an observatory stage(SMG) without those portal things
and(from FE RD)[Spoiler]Ashera's tower without a barrier(you know, the part where you fought the black knight[/Spoiler]
