Skip Steps with JSONRPC

Hello,

is there any possibility to use the new (since v15) skip steps feature using jsonrpc commands?
Or is it possible to simulate keypress (right, left) with jsonrpc to get the same effect?

Because I find the new skip_steps (wiki) perfect, but they only work wit real remote controls or keyboards, but not with my App on Android phone, because this uses jsonrpc commands to control Kodi over network.

Thanks!
