Ability to create/insert snippets anywhere within a note

Would love to have this feature, which is kinda similar to email snippets. Basically it's like Amplenote templates except you don't need to create a new note. You can simply insert data you repeatedly use anywhere within an existing note.

For example, I can insert Author/Contacts' metadata of a person that came up as I write my notes (like Full Name, How We Met, Company Affiliations, etc).
