Support subitem columns in Slack integration notifications

By today, the Slack integration only supports item columns in the notify message. I need it to support subitem columns (e.g. subitem’s name, subitem’s status) in the notification. Ideally, all types of column that are supported for items should be supported for subitems. This is especially important when the trigger clause refers to a subitem column, like subitem status.

yeah it is really crucial features that monday need to add urgently because when sub-items columns messages are required to be provided on slack then its next to impossible despite of very important features.
