Using candumps instead of live traffic from interface

Would it be possible to adjust canopy to also allow for the visualization of recorded candumps instead of connecting to an interface? I have recorded several candumps and would like to analyze them using canopy for reverse engineering.

e.g. for candump message format
(1620458408.814144) can3 0C000003#0150140000000000
(1620458408.814144) can3 0CFF0303#6400000000000000
(1620458408.814144) can0 069#9102460028284600

These logs can be visualized by setting the config to a virtual interface and redirecting the output to the same interface with canplayer.

For example, if you have pre existing logs that were originally recorded using can0 the command would look like --
canplayer -I candump-messages.log vcan0=can0

Thank you for the question -- I should add better documentation to address this as it's definitely a useful feature.
