Pulldata is perfectly compatible with select on questions. However I'm struggling to understand what you want to do, or why. If I understand correctly:
Your aim is to reduce errors and time.
The sample information for each project is invariant and project specific.
There can only be one correct value for sampinfo_type for any project.
If that is the case, I can't understand why you are asking your operators to provide you with the values for sampinfo_type by selecting one correct answer from a list of many. You know already know what the single correct answer is, why don't you just present that value as a note to tell the operators, rather than asking them to tell you? That would save time and and reduce errors.
The only way I can see this making sense is if the sampinfo_type has multiple possible values, and you only want the operators to be able select the values that are possible for that project. It' simple enough to do that using a cascading select select_one_from_file.
I've attached an example table below presenting both these options Hopefully one will provide enough info to construct what you want.
