Combine Batch Job logs under BatchHeader

I have extended a batch job which creates multiple tasks using the RunBaseBatch framework

However, when it logs errors it logs them under the batch task and they're not immediately visible against the header logs

So they end up looking like this when pressing the log button from Inquiries - Batch Jobs - Batch Jobs

Infolog for task Batch Update 
1 batch tasks created
The batch job Batch Update completed successfully.

But the warnings can only be seen when you click on batch job history and then click on Log
