Is there a way to adjust the base temperature of my Ecobee3 Lite thermostat without disabling eco+ for the entire day?

I'm aware that eco+ operates by reducing the temperature by a certain offset in advance of a higher peak period coming up, then increases the temperature by a certain offset once it has come up.

However, when I adjust the temperature in any way, the thermostat will require me to first suspend eco+ for the whole day before I can make the change.

Is there a way to adjust the base temperature from which the offsets are calculated without having to disable eco+ for the whole day? I've tried following its instruction to suspend it then going into the settings to disable and re-enable eco+, but this hasn't worked for me always.
