Great utility (a bit expensive thou 25+VAT which makes it $29 US) for autosync folders within premiere and after effects and import batch sequences (A functionality missing in Premiere for which I wrote a workaround a few years ago https://cocoalopez.com/blog/?p=2892 )

But this tool keeps everything in Sync without the need of reloading.
