property tree in specifications - add new node on the fly ?

Hi Gurus,

I was working with specification management. We have property tree nodes for a specification type, which is standard.

I was looking for a way to add a node on the fly, to include in the tree. I dont know why its not possible, do we have to

go to img to add it in config ? Also if we wish to delete one node from the tree, its not possible. Why ??

Is there any BADI or any functionality provided by SAP which I could not find ?

I wanted to reach out to community before creating a OSS message.

Please let me know Gurus ..

Thanks

Devi
