Is there a way to change filter's Cutoff Frequency continuously in blueprint?

I want to change filter’s frequency continuously.

‘TimeSynth’ clip has ‘Filter A’ and ‘Filter B’.
And ‘Source Effect’ and ‘Sound Submix’ also have ‘Filter’ effect.

But their ‘Cutoff Frequency’ parameter seems to be static.
It seems to have noway to change dynamicly in blueprint.
Is there a way to change frequency dynamicly in blueprint?

(changing filter ON/OFF is not continuous change.)
