user definable commands

[mcfiredrill]

can users/dj accounts define chat triggers/aliases? like is there a way for me to do like !shoprequest or something that can spit out a string like "MAGENTA: REQUESTS HERE>> server.com/pagelink.html"

i know its like, probs admin-doable but i was just wondering if there was a like a cmd do it as a chat/chatbot command
not like it's an issue to just paste the link instead of an alias ha but yeah just curious
