Multiple choice - searching any part of the text

Hi there,

I am new to Sharepoint, and trying to figure something out that I assume is simple.

I have a column in an item form that is multiple choice, with many options. 
When a user is creating a new item, and are choosing an option in this column, I'd like them to be able to start typing any part of the choice, and have it come up.

By default, it searches only in the exact order you type, and you have to correctly type the first letters of the choice.

For example:

For the option "Computer Services 107" - If they start typing Com, or Ser, or 107, I'd like it to jump to this option. Currently, unless they type Com - nothing comes up.

Possible?

Thanks,

Amber
