SPIFFS Upload - dont overwrite other Files

Hello,
im building a Weatherstation with the esp32, where many sensorvalues are getting stored in a SPIFFS log file (dynamic creation). i also have a webserver with html files in the SPIFFS.
When i want to upload changes of the html files via platformio upload file system image, these log files get deleted.
Is there a way to keep these files, while uploading the html files?

Regards,
