Allow mapping to Asana multi select field type

Our development team is currently using Asana to handle their tasks.

We are sending our features over from Aha to Asana and also importing features from Asana to Aha.

We have some custom fields that are Predefined tags fields in Aha. For example to represent which area(s) of our application is affected by the feature. We can select many areas, so it's a "multi-select" field.

Currently, we can synchronize this with a text field in Asana...However, we would like to sync it with a multi-select dropdown in Asana because with the text field synchronization, we can't enable a "bi-directional" integration. We can send things over from Aha to Asana, but can't from Asana to Aha...So this means that when things are created in Asana (and then imported into Aha), we have to manually go over all these custom fields in Aha and populate them afterwards. Since developers don't have an account in Aha, this means that it's the product managers that needs to populate these fields in Aha (even when the developers would have been able to populate them by themselves on Asana).
