Online resource for mana fixing

[EtherealKris]

You know how on MTGO in drafts and sealed events they have the "suggest mana" option... Is there any site online that I could potentially put in a pool of cards for a deck and have it help me with my mana?

Not sure of any auto website, but this might help somewhat.
