Slack Polling Rate

I have Asana integrated with Slack to send updates to my @Slack user. However, the polling rate seems to be short. I’m getting updates to my Slack user channel about once per minute. When creating an Asana task or note, I frequently make take 5-20 minutes to refine it. This results in a lot of notifications to Slack on the same tasks. It would be great if we could change the polling rate of the integrations to more closely match our work.
