Adjusting gridGlobalOffset and temporal offset about smilei HOT 7 OPEN

I am interested in a solution that works before post-processing. The proposed solution with happi goes against all efforts of the openpmd standard.
Therefore, I would highly appreciate if you could add this feature (or propose some kind of workaround that works before post-processing).

I have the same problem. It would be really helpful, if it could be implemented before starting the simulation.

Or is there a way to manually change values in the hdf5 via a command in the namelist?
Then I could use this as a workaround and manually set the desired values for gridGlobalOffset and the temporal offset.

This can be done at post-processing time using happi:

arguments xoffset, yoffset

Why do you need it at the beginning if it can be changed afterwards?

I want to be able to use the same tools for visualisation for all my simulations (also independent of the code they were compiled with). Thats what the openpmd standard is for...

One could argue that defining an arbitrary offset should be done during post-processing and not pre-determined and definitive because you might want to change your mind and be able to use different offset for the same data.

So maybe a request on the side of the viewer you are using to implement xoffset and yoffset as in Happi would be relevant ?
