Copypasta or symbol quick access like emotes

Requesting an interface that can store long texts, or even just symbols like 8(>,<)8====, and map it to a name of user's choice to be accessed like emotes. For example, i can save 8(>,<)8==== as :jealous: and it will be an option for me to choose when i do :jeal, along with other emotes that might come up. This way not only can you do copy pasta but also text based emotes which is common in japanese texting to be streamlined. In addition the text saved/mapped should also keep the font or modifiers like bolden, italics in tact.
