Request for Custom Stamp Functionality in Canvas

The stamp feature in Canvas is difficult to use from users in Japan. The main reason is that the symbols we commonly use are not available and the shapes are not unfamiliar.
This stems from the fact that Japan uses a standard called JIS, which defines the standard symbols used in piping and instrumentation diagrams. (In the U.S., this would be like ASME and ANSI.)

“Add JIS-defined symbols” could be a solution, but many other countries also have their own standards.
Supporting each of them individually would be impractical.

Additionally, different industries outside of oil & gas may require different sets of symbols.

Therefore, I would like to suggest adding a feature that allows users to upload their own custom stamps.
More specifically, we could upload an image with specified a size to a dataset and use it as a stamp.

The reason for specifying a size is that very large images would not be appropriate as stamps. 
Something around 40×40 px seems reasonable.

It would be great if you could consider this.
