How to read/write pose to variable

Hello.

I have tree questions and it will be great if I get an answer to one of them.

Question #1. I have a script that creates pose file with this code

...

var fi = DzFileInfo(sFile);
oSettings.setBoolValue( "RunSilent", true );
oAssetIOMgr.doSaveWithOptions( oAssetIOFilter, oSettings, false, sFile, fi.path(), "" );

...

It creates pose file with thumbnail. The only thing that bothers me here is...

thumbnail, right. Is there Setting that forbides thumbnail creation?

Question #2. I have a pose file and script that applies that pose file to selected figure via openFile() function. The only thing that bothers me here is pose file. What about hardcode? Is it possible to prescribe that pose to variable in the script and then apply it to selected figure? What function?

Question #3 is similar to previous, but not the same... I have script that creates pose file from selected figure first, does some weird things with figure :) and then applies that pose with .openFile() function. The only thing that bothers me here is...

pose file creation, right. Is it possible to write pose to variable and then apply it to figure? What functions do this?

Thank you.
