I've been searching for an answer to this for a bit now and im not sure how to accomplish the following.

with the fallback option, lets say i was mining litecoins on pool x with the scrypt flag (obviously) and wanted to fallback to a bitcoin pool if the litecoin pool was down. What would be the best way to accomplish this. is there a way to disable the scrypt flag once its been launched with scrypt or what do you guys think my best solution would be to have something like this work. another option i could do if possible is change it through the api but im not aware of algorithm changing being a cgminer api option. thanks in advance guys.
