Is there any way in Sage 2013 to block export to Excel from an Advanced Lookup?

SUGGESTED

Is there any way in Sage 2013 to block export to Excel from an Advanced Lookup?  Will be upgrading to 2017 but not until late this year.  Basically, I want to prevent anyone from seeing item cost in Item Inquiry - I've hidden those fields using Custom Office for screen presentation, but all they have to do to bypass this is use Advanced Lookup, select the cost fields and export to Excel.  In a perfect world, I'd also like to prevent customizing the lookup itself as well.

THANKS for any help!
