Substring replace?

[epixoip]

Table attack was only supported in hashcat-cli (now hashcat-legacy) and could only match a single byte. It is similar to the 's' rule but could replace one byte with multiple bytes, which the 's' rule cannot do.

Matching multiple bytes in the manner you described would indeed be powerful, but would likely be really slow. But maybe speed is a worthwhile tradeoff for such a rule.
