Today it is not possible to use TRAVERSE clause in creating a segment in the RTM segment builder. This is something that we can do in the Outbound segement builder.

This means that there is no possibility to segment on child account data where the only connection to contact/lead exists on the parent account..

The parent/child relationships are standard (OOTB) relationships that can be used to create segments in Ooutbound Marketing bu not in RTM. This has to become possible in the new segement bilder in RTM.

Please vote to get this functionality in to RTM ASAP!
