Use First Paragraph as Post Description

Hi,

when using this dynamic variable %%post_excerpt%%, if the excerpt is not available, we’ll use your post content as a fallback.

Can I just use the first paragraph?

Without custom dev, this is not possible (https://www.seopress.org/support/guides/create-your-custom-dynamic-variable-for-your-meta-title-description-social/).

To be honest, there isn’t any interest doing this.
