Robopacers changing w/kg on intervals

Hi,
It would be nice (at least for me) if robopacers could change (let’s say on daily interval) the w/kg by for example from -0.1 to +0.1 around it’s current static w/kg. Meaning let’s say Bernie would be riding 1.4 w/kg on Monday, 1.5 on Tuesday and 1.6 on Wednesday. That could cover all w/kg almost continuously and allow to chose the right robopacer in advance for better training planning.
