A few questions about the Metamorphosis power from Psionics

[Gutsigrit]

Firstly, apologies for my ignorance on this matter. I am making a psychometabolist psion (egoist) for a campaign. I am curious about the metamorphosis powers available but I am unsure if they have some specific limitations. I realise someone can change into creatures or objects of their size whilst retaining their weight. However, is it possible to change your appearance after the spell has been cast? For example, if I have turned into a rug or a chair, can I then make myself look like a human or turn into another object like a painting all whilst under the same spell (since it lasts 1 min/level)? Also, can the metamorphosis spell be dropped? So if you are a chair, do you have to be a chair for the spell’s duration or can you revert back to your normal self?
I would be very appreciative of any and all answers. Thank you.

While I believe that 3.5 version allows you take on the form of a object, I don't remember if the dreamscarred press pathfinder version does. As for being able to continuously shift shape while the power is active I don't think so. But as I understand the rules you can with a power with a duration longer the one round pay any augment that you haven't already at any point. For example you if you manifest minor metamorphosis without initially augmenting than pay any of its augment coast, then at any point during it's duration pay any of it's augmentations coast adding new menu selections.
