American Express Membership Rewards - Crediting Membership rewards with AC miles.

Simple question, can't find the answer elsewhere and a search on this site did not pull up any answers.
I have about a million miles in aeroplan; is there any way to convert these to AMEX MR points, or is it simply a one-way street? The AC program is really not very good and i would like to have more options for carriers and for hotels.
thanks

Sorry, this is a one way conversion from Membership Rewards to various airlines, nothing in reverse. I suggest you spend time in Flyertalk"s Aeroplan forum where you can learn how to redeem through Aeroplan for travel on any Star Alliance airline.

thank you, i was afraid that was the case. I'll keep trying to book something worthwhile with aeroplan then!
