[O] org-babel: insert named source block

[Deepak Cherian]

Has anyone here managed to configure ivy or helm to show a list of named 
source blocks that org knows about?

I am imagining this workflow:
1. M-x org-babel-insert-named-source-block (imaginary function)
2. List of named source blocks pops up
3. Hit enter and "#+call: name-of-source-block()" is inserted at point.
Thanks,

Deepak
