People on Discuss are from different backgrounds, timezones and work/life balancing. You cannot expect that someone who knows the answer is actually be online. As such your impatience comes over as very unfriendly.
This. You can't expect someone to be online at all times, especially for a free and community ran service that is not even affiliated with Flarum. Also keep in mind that we might not be able to answer questions that are not related to FreeFlarum directly (your question was about Flarum or its extensions). Examples of questions/concerns related to FreeFlarum: "My X forum is down, can you help?", "How do I link my custom domain?", "Can you delete my forum?" and similar.
I fully agree with what @luceos said, and I am pretty busy right now with different FreeFlarum related things. If you have a question not related to FreeFlarum, please open a new discussion at this forum. People don't usually browse this thread looking for Flarum questions, because this is expected to be a FreeFlarum thread (not "Flarum FaQ" or whatever). If you create a new discussion in the appropriate category, the odds of your question being answered rapidly increase. I am glad that these "off-topic" rules are being enforced more, because it helps this forum to stay organized and tidy.
As for your question, it's not possible but an extension might be able to do that
