I would like to be able to pin AI models in the assistant dropdown for easy access.
The list of models is getting pretty long (I love having options), so I think being able to pin your favorites right below the Custom Assistants section could be a very nice usability feature to add

Personally, I use about 3-4 different models depending on what exactly I'm doing. Being able to pin those models, would help me to quickly find/choose the specific model I need for the task without having to create a custom assistant just to have it up top.
