Base upgrade all

So i run Building Grades https://umod.org/plugins/building-grades  but I have people doing the following and making out there XP just for doing a building upgrade. 

We found a way to get a ton of xp. we build a 10x10 and make it 4 stories tall then /upall 2, then upall 3, then upall 4. and we get about 100 levels from it. you have to be super stacked on mats so not sure if its really an issue. just letting you know if u want to neef xp from building/upgrading buildings

Is there anything I can do in the config to block this I know Building Grades do not have a setting but wanted to see if you had anything in the config to block this. 

There is a building xp delay option to help prevent this.
