Auto-Comment for Facebook Group Post

Question

I've posted a pre-launch announcement for a new product in an active group and I got 2500+ comments from people who want to get the product. I want to respond to each single comment with the details when I will launch it into the market. If there any method, script, or a free software to do that?

Edit: I wonder could it be done by a script using Greasemonkey? addons.mozilla.org/en-us/firefox/addon/greasemonkey

There is no way to comment in groups anymore:

90-day Deprecations in Graph API v2.10

POST and DELETE operations for the /{comment-id} node and the /{object-id}/comments edge will now be restricted to Pages with valid page access tokens.
