Sendgrid ASM in node

Good day.

Current Sendgrid node doesn’t have asm (advanced suppression manager) among additional fields listed for dynamic template.
This field is used by Sendgrid to correctly set unsubscribe link in email, without it link looks something like this:
x-webdoc://02725D1E-9E30-4346…/%3C%25asm_group_unsubscribe_raw_url%25%3E

In JSON it look like this: “asm”:{“group_id”: 12345, “groups_to_display”: [12345]}.

Here’s additional info about API: Mail Send | Twilio.

Would it be possible to add that field? Or may be there’s a way to append this data to API call?

Thanks.
