Those Flipbooks come with a special Event, that fires, if the Flipbook reached its end (however, works for Non-Looping Flipbooks only). You can use that to build a counter and compare a value with your desired number of loops, and once the number is reached, you can change out the Flipbook with a new one.
Since it will only work for Non-Looping Flipbooks, you can temporarily turn off the Looping ability in your blueprint so that you don´t have to mess with all your flipbooks just for this.
A quick and dirty, and not very elegant, but working example.
