I am not familiar with clicking on redundant UI selectors; I know there is a way to say, click on 1st UI = Generate, click on next UI = Generate, but I don't know enough about it.
If I were building this, I would assume this site accepts Send Keys {Tab} to use as a selector, and then I could go into a loop:
Loop using LoopIndex 200 to 6000 increment of 200
Loop using LoopIndex 1 to 200 increment of 1
If LoopIndex = 1
Send Keys {Tab} 'as many tabs as you need to get to the first Generate
End If
If LoopIndex >1
Send Keys {Tab}{Tab}{Tab}{Tab}{Tab} 'looks like 5 tabs to get to your next Generate
End If
Send Keys {Return}
Whatever other commands you need to save your file and get back to the website screen
If LoopIndex = 200
Send Keys {Tab} 'tabs to get the next page icon
Send Keys {Return}
End If
End Loop
End Loop
Best of Luck.
