I'm working with multiple spatial transcriptomics samples, I started by making spe for each sample, and then when I tried to combine them using 'cbind' it took so much time. is there any other easy way to combine them in a single spe object and why it takes that much time?

# spes is a list of multiple spe 
spe <- cbind(spes[[1]], spes[[2]], spes[[3]], spes[[4]], spes[[5]], spes[[6]], deparse.level = 1)
