Can boxcryptor double encryption with another solution?

I would like to double encrypt my cloud storage with 1 first, and then the other.
Can boxcryptor work with any other one?

Thanks.

I made a wordpress page about my trial:
https://wordpress.com/page/bullshitmanblog.wordpress.com/73

will try to summarize my trial and errors at a user level.

oh the link should be this one instead:
