So yeas, I made it with the help of [this post][1] that have missed before, my apoligies, just needed to manipulate the coords from blueprint using Delta Seconds being able to store the two variables X and Y without the panner like this
On the blueprint I’ve set up the dynamic material named Clouds Material then created 2 new float variables OffsetX and OffsetY, 2 functions for updating the offsets to finally set the parameters to the Material
Then all is get the parameter from the collection for each coord, X and Y, creating two functions, multiplying the delta with the speed adding the offset with the modulo and setting it for each one
And that’s how I have beem able to track the coords and change the speed seamlessly without losing the texture position 
if there’s a better approach it will be much appreciated !
