Multipart Ladders

[Thutmose]

I would like to make a multipart which can be used as a ladder, but

public boolean isLadder(IBlockAccess world, int x, int y, int z, EntityLivingBase entity)

is not forwarded from the block to my part. Could this method also be called for the part?

if there currently is a way to make it act like a ladder besides that method, please let me know.
