setTimeStep additional functionality

Goal: at certain time switch from adjustableRunTime, adjustTimeStep to full control:

• ramp time step
• suppress writing

Can this be done through setTimeStep FO?

E.g.
up to time 1: adjustableRunTime, write interval 4.
from  1 to 2: ramp to e.g 0.1s
from 2 to ..: 0.1s

Time        DeltaT
----        ------
            adjustable
1           ramping to user defined
2           user defined
3           user defined
4           user defined + write as specified by writeInterval
(so only write at end of simulation)
