Hi Yepestis,
Unfortunately, such a feature has not been included yet in our latest firmware release. However, we will keep an eye on more requests to send them as new feature recommendations to our RnD department.
Below, I will drop a link where you can find the firmware changelog, which specifies our latest firmware's new features, improvements, and fixes.
