create a campaign with content

[hojat-a]

According to the mailwizz document, user can utilize a html file as template content.

    # required block, archive or template_uid or content : required.
    # the templates examples can be found here: Examples
    'template': {
       # 'archive': File.read('template-example.zip'),
       # # 'template_uid': 'template_uid',
       'content': File.read('template-example.html'),
       'inline_css': 'no', # yes | no
       # 'plain_text': nil, # leave empty to auto generate
       'auto_plain_text': 'yes', # yes | no
    },
    })

I will be grateful if someone add this feature to the module.
Thank You.
