Feature request: save constants from previous uploads

[VDK]

Would be nice if when you switch on a particular value being a constant, the value you used for that constant on a previous upload would appear.

I upload a fair few of my own photographs using Pattypan, so I keep putting in

{{own}}
[[User:1Veertje|Vera de Kok]]
{{self|CC-BY-SA-4.0|author=Vera de Kok}}

for source, author and license.

I like Pattypan a lot more than Commonist, but this is one thing that Commonist has that Pattypan doesn't.
