I think you are being presumptuous that if someone has a 4 Byte ASN they have to have a 64 bit community. Standard BGP communities are defined as 32bit, using the ASN as the first part of the community is only a BEST Practices and not a Technical Requirement. i.e. there is nothing stopping you to have a community defined in your network where the first part is not your ASN.
Extended BGP Communities can be 64 bit, and yes current version of MT does not support them. Having said that, I would suggest that you contact your upstream and ask them if they have a Standard 32 Bit Community which would allow you to do what you need.
