Doctype list Hook not Running

@makarand_b I think it is possible, seems like a few of us could do it. Here is one:

Add to doctype's list js via hooks

I created a custom app to print Payin Slips from JV’s list view. To do so i needed to alter list js for JV. Is there an existing way to add to list js of a doctype with out altering original/erpnext app files? If not, can i raise a PR to add to list js via map in hooks.py? eg usage for hooks approch. doctype_list_js = { "Journal Voucher": ["c_scripts/journal_voucher_list.js"] }
