Sure... yes, ask her for a referral. It's reasonable to want a local, and 40 miles is a long ways if you will likely make repeated trips to look at places.
The referral is the best option for her. Hopefully she'll do some research... interview and find a good agent for you up in the area you're going!
BTW, if her portal isn't showing you "everything" you're seeing elsewhere... consider that the criteria you gave her is perhaps different or more restrictive than the one you use browsing on Zillow or Realtor. She has many more search tools and criteria available to filter the results by than you have on those public sites. Sometimes more is good, if your criteria are not set in stone... sometimes more is NOT good, if the extras you're getting don't really fit the criteria you want, or they aren't even accurate or currently available for sale, as often happens with Zillow.
My two cents.
