Okay I need it

Yes agreed but also allow merging of transactions on different dates. This in order to combine hundreds of small reward amounts and sum weekly or monthly for example. It is ridiculous to have large numbers of tiny amounts. I'm sure tax offices would not object and in any case the tax effects would mostly average out close to zero over long periods. I already do this but it has to be done manually which is extremely time-consuming and prone to error.

Actually, you can merge 50. You need to merge in multiple groups of up to 25 each, then you can merge those groups up to a total of 50. However, I'd like to be able to merge 100 or more.

As retail focused on-chain tools increase in complexity there will be more and more need for this imo. One example is the Jupiter dex on Solana which allows users to DCA across dozens of transactions when buying or selling tokens - see https://jup.ag/dca/
