Bahmni Powdered Type Drug

I am strugling to allow Doctors to enter powdered type medication. Powdered type here means the powder mainly consist of several drug type that are mixed together. Also, the combination is limitless thus I can’t set a fixed list of the possible combination.

As long as the drug order can be synced to openerp it’s considered a done deal.

Any idea how can I do this in Bahmni? Any workaround also welcomed. Thanks.
