Aliases variables in docx files using Jinja2's {% set %} and {% with %} syntax

[lishuaijiang]

I attempted to use jinja2's {% set %} syntax to set variables aliases in the docx file, but it didn't work, and I couldn't find the usage of set aliases in the documentation.
It seems that set aliases is not supported at present, have you considered adding it? Similarly, jinja2's {% with %} syntax is not supported.
