Is there a way to save animation preset by script?

Hello,

    I have written a script named Memory,which save any layers even comp layer for later generating.https://github.com/Smallpath/Memory

    A few days ago,I completed the preview feature,and was ready to release it with v3.0 tag.However,script can't get or set the value of special plugins such as Curve,Particular and Puppet,nor do my script Memory.I know these plugins can be saved as animation preset by click in Ae,but that needs the user to click, select the folder,input the preset name and finally click OK,which is not I what.

   I really what to improve my script.Therefore,I wonder if there is a way to save animation preset by script.Maybe it can be a hidden method such as CompItem.saveFrameToPng.Thanks for any help
