You should be able to do it from FTM, Marg. I've used it before to create a tree for just one grandparent, and I tried it out again just now to make some instructions on how to do it:
File - Export - choose output format required
Where it says "Individuals to export" choose "Selected individuals"
On "Filter individuals" pop-up,
click on name of grandparent then click "ancestors", then on Ancestors pop-up, choose "Include all parents", "Include all spouses", and "Include ancestors' descendants" and set the number of generations to the max allowed. Then click "OK". Then when it comes back with number of individuals included in filter, click OK again (assuming the number looks about right), then click OK again and it should ask you to give the file a name and create it.
