[NEST Users] Access weight_recorder data during simulation

Dear all, I was wondering if it is possible to access the events collected by a weight_recorder during a simulation: I am able to collect and plot the recorded data once the simulation is over, but I found no information about accessing the device in real-time. Specifically, I would like to know if there is a way to pass the data as input to a custom NESTML synapse model dynamically during a simulation.

Best regards, Francesco Sheiban
